Many magnetic reed sensors on esp8266
Posted: Sun Sep 04, 2016 2:15 pmHi,
I want to connect 2 magnetic reed sensors to my yellow board esp-12E, but only one sensor works. On two GPIO pins I set input pullup and it works only on gpio2. Below i shows a part of my code.
What am i doing wrong? Only one gpio pin can works in input_pullup mode?

Code: Select all
void setup() {
Serial.begin(115200);
Serial.println();
pinMode(2, INPUT_PULLUP);
pinMode(12, INPUT_PULLUP);
}
void loop() {
int x;
int x1;
if (digitalRead(2) == HIGH) {
x = 1;
}
else {
x = 0;
}
if (digitalRead(12) == HIGH) {
x1 = 1;
}
else {
x1 = 0;
}
}
